Newcastle United have enjoyed a decent start to life back in the Premier League having picked up the Championship title last season.

Most players look like they have settled in comfortably despite the step up in class, with Benitez getting the very best out of the majority of his stars.

Matt Ritchie has proven he has what it takes to shine in the Premier League, after Bournemouth let him drop down to the Championship to link up with the Magpies.
